A suction caisson system comprising a caisson body comprising an upper rim, a lower rim, and a weakened section positioned between the upper rim and the lower rim. The system further comprises a caisson cover constructed and arranged to detachably connect to the upper rim of the caisson body as well as a pump constructed and arranged to provide fluid to and from the interior of the caisson body. In the event the caisson body is impacted by an advancing ice keel, or other foreign object, the caisson body will be sheared at the weakened cross-section, thus protecting any subsea equipment positioned within the caisson body below the weakened section.

Suction caisson with weakened section and method for installing the same

A marine vessel for hydrocarbon exploration and methods of utilizing the same. In some embodiments, the vessel is enhanced with deployable and adjustable land propulsion mechanisms controlled by an active system to maintain position when on top of a drifting ice floe, water propulsion devices connected to the vessel hull capable of station-keeping in open water and/or within broken sea ice, sufficient power and flexibility to enable riding an ice floe, and at least one deployable ice hole cutter to open a channel through the ice floe.

Arctic walker for hydrocarbon exploration

A system and method of drilling oil and gas wells in arctic or other environments having adverse conditions. A marine hydrocarbon operations structure may comprise a caisson body having a top surface which defines an opening and a shaft positioned within the opening. The shaft has an engagement member positioned on the external surface of the shaft. A lower jack house system is constructed and arranged to change the vertical position of the shaft through interaction with the engagement member. An operations platform supported by the shaft.

Arctic telescoping mobile offshore drilling unit

A mooring system for a floating vessel such as a drilling unit is provided. The floating vessel has a platform for providing drilling, production or other operations in a marine environment, and a tower for providing ballast and stability below a water line in the marine environment. The mooring system generally includes a plurality of anchors disposed radially around the tower along a seabed, and a plurality of mooring lines. Each mooring line has a first end operatively connected to the tower, and a second end operatively connected to a respective anchor. Each mooring line further comprises at least two substantially rigid links joined together using linkages. Each joint is at least five meters in length. The mooring system is capable of maintaining station-keeping for the vessel greater than about 100 Mega-Newtons such that operations may be conducted when the marine environment is substantially iced over.

Mooring system for floating arctic vessel

Method and apparatus for extending the horizontal distance through which wells can be drilled. A horizontal tubular is used to convey a drillstring from a drilling rig toward a target location and a mud return line and pump on the surface is used to pump drilling mud returning from the bit back to the drilling rig.

System and method for drilling a well that extends for a large horizontal distance

Compliant offshore platforms with isolated decks using one or more bearings located on a generally horizontal plane that is in proximity to the vertical center of gravity of the deck.
